Treatment of megaesophagus with forced dilatation of cardia through hydrostatic balloon attached to a fiberesophagoscope.

The treatment of megaesophagus through the forced dilatation of the cardia has been used in Brazilian medical centers for the treatment of megaesophagus in the initial stage. In patients with advanced megaesophagus without surgical conditions due to the involvement of various systems or those who present severe degrees of malnutrition it is necessary to perform the dilatation of the cardia even with an temporary effect for the improvement of the general condition. The dilatation balloon usually employed does not permit the device to be used safely due to the deviation of the axis of the distal third of the esophagus. A hydrostatic balloon attached to the fiberesophagoscope was adapted to allow the dilating apparatus to be introduced under direct vision for greater safety. Twenty-one patients were treated under the above mentioned conditions and the results justified the indication.

Rectal sphincter reconstruction in perineal colostomies after abdominoperineal resection for cancer.

A surgical technique is proposed for the reconstruction of the anal sphincter in perineal colostomies after abdominoperineal resection for cancer. The procedure, which employs the gracilis muscle for the sphincteric reconstruction is described and the operative results and complications are analysed in 24 patients submitted to this type of surgery. Of the 22 patients who were followed up, 17 had excellent or good results with retention of solid or soft stools. Three patients had poor results with no voluntary retention, while 2 others were partly incontinent of solid faeces. In this group of 5 patients, 3 had stenosis of the colostomy and 1 had no sensibility of impending defaecation.
